Sometime this summer or fall I want to set up a family gathering with some family that we normally just see at Christmas. If we gather at my grandmothers in June then I would do my party in the fall and if we don't in June then I would do mine in July or August. The ages range from grade schoolers to people in their 30's and then old folks (aunts and uncles) in their 50's and 60's and a grandmother who is 88. What kind of fun events would I have as it would be at a public park.
